So, you want a thinner, wider, shorter, taller whatever model with clothes on, but you don't want to spend eight hours adjusting all the clothes to fit right, follow the morphs, whatever. Well, why not try adjusting your camera scale instead? You can stretch and contort your model and all her conformables with one quick spin of the dial. You want shorter? Just turn up the camera's y axis to about 110 percent. Etc. Try it out! -Darth_Logice

...but doesn't everything else in the scene get sized too?

Yes, obviously, but it's good for just figure shots, which a lot of us do. -Darth

I wonder if this can be used to make anamorphic images that would be unsqueezed on playback on widescreen monitors?

I don't know the answer, but I won't let that stop me from answering your question. In film widescreen movies are shot with anamorphic lenses and played back with anamorphic lenses. The reason is that film has a finite width. So to get more width info on the film you have to squeeze. It would seem to me that you don't have this constraint in the digital world, since there is no (reasonable) limit on width - therefore no reason to squeeze. Shoot wide, play back on a wide monitor.
